[Saxon-HE 10.3] DocumentOrderIterator::next seems to be looping forever

Hi,

My application started hanging when I added several templates like
this to imported stylesheets:

    <xsl:template match="*[@rdf:about = '&nfo;FileDataObject']" mode="ac:label">
        <xsl:apply-templates select="key('resources', @rdf:about,
document('../translations.rdf'))" mode="#current"/>
    </xsl:template>

I traced it to Saxon and I can see the file is being read, but then
the evaluation is looping over multiple calls but always coming back
to ItemMappingIterator::next (stacktrace below).

Is this a known issue? Should I try a newer version?
